Expansion cards and expansion card riser

An expansion card in the computer is an add-on card that can be inserted into an expansion slot on the

computer system board or riser card to add enhanced functionality to the system through the expansion

bus.

NOTE: A System Event Log (SEL) event is logged if an expansion card riser is unsupported or

missing. It does not prevent your system from turning on and no BIOS POST message or F1/F2

pause is displayed.

Expansion card installation guidelines

NOTE: Only supported cards from Dell can be installed in the system.

Your system supports Generation 3 cards.

Cooling shroud

The cooling shroud has aerodynamically placed openings that direct the airflow across the entire system.

The airflow passes through all the critical parts of the system, where the vacuum pulls air across the

entire surface area of the heat sink, thus allowing increased cooling.

System memory

Your system supports DDR4 registered DIMMs (RDIMMs). It supports DDR4 voltage specifications.

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

Memory bus operating frequency is 2133 and 2400 MT/s based on:

•

System profile selected — Performance Optimized.

•

Maximum supported DIMM frequency of the processors

Your system contains 12 memory sockets split into four sets— two sets of 4 sockets and two sets of 2

sockets each. DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B4 are

assigned to processor 2. Each 4-socket set is organized into two channels and each 2–socket set is

organized into one channel. In each channel of the 4-socket set, the release levers of the first socket are

marked white and those of the second socket are marked black. In the 2-socket set, each release lever is

marked white.

Figure 15. Memory socket locations

Memory channels are organized as follows:

Processor 1

•

channel 0: slots A1 and A5

•

channel 1: slots A2 and A6

channel 2: slots A3 and A7

channel 3: slots A4 and A8

Processor 2

General memory module installation guidelines

NOTE: Memory configurations that fail to observe these guidelines can prevent your system from

booting, stop responding during memory configuration, or operating with reduced memory.

The system supports Flexible Memory Configuration, enabling the system to be configured and run in any

valid chipset architectural configuration. The following are the recommended guidelines for installing

memory modules:

•

Up to three dual- or single-rank RDIMMs can be populated per channel.

If memory modules with different speeds are installed, they will operate at the speed of the slowest

installed memory module(s) or slower depending on system DIMM configuration.

•

Populate memory module sockets only if a processor is installed. For single-processor systems,

sockets A1 to A12 are available. For dual-processor systems, sockets A1 to A12 and sockets B1 to B12

are available.

•

Populate all the sockets with white release tabs first, followed by the black release tabs, and then the

green release tabs.

Populate the sockets by highest rank count in the following order—first in sockets with white release

levers, then black, and then green. For example, if you want to mix single-rank and dual-rank memory

modules, populate dual-rank memory modules in the sockets with white release tabs and single-rank

memory modules in the sockets with black release tabs.

•

When mixing memory modules with different capacities, populate the sockets with memory modules

with highest capacity first.

In a dual-processor configuration, the memory configuration for each processor should be identical.

For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and

so on.

•

Memory modules of different capacities can be mixed provided other memory population rules are

followed.

Populate four memory modules per processor (one DIMM per channel) at a time to maximize

performance.

Mode-specific guidelines

Four memory channels are allocated to each processor. The allowable configurations depend on the

memory mode selected.

Sample memory configurations

The following tables show sample memory configurations for dual processor configurations that follow

the appropriate memory guidelines.

NOTE: 2R in the following tables indicate dual-rank DIMMs.

WARNING: The memory modules are hot to touch for some time after the system has been

powered down. Allow the memory modules to cool before handling them. Handle the memory

modules by the card edges and avoid touching the components or metallic contacts on the

memory module.

CAUTION: To ensure proper system cooling, memory module blanks must be installed in any

memory socket that is not occupied. Remove memory module blanks only if you intend to install

memory modules in those sockets.

Steps

1. Locate the appropriate memory module socket.

CAUTION: Handle each memory module only by the card edges, ensuring not to touch the

middle of the memory module or metallic contacts.

2. To release the memory module from the socket, simultaneously press the ejectors on both ends of

the memory module socket.

3. Lift and remove the memory module from the system.

socket, and insert the memory module in the socket.

CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both

ends of the memory module evenly.

NOTE: The memory module socket has an alignment key that enables you to install the

memory module in the socket in only one orientation.

3. Press the memory module with your thumbs until the socket levers firmly click into place.

When the memory module is properly seated in the socket, the levers on the memory module socket

align with the levers on the other sockets that have memory modules installed.
